Volcano Calendar 2019: We're proud to present our 2019 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.

The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.

The ongoing eruption at Veniaminof (which began on September 4) has intensified today, with a significant increase in seismicity and now-continuous ash emissions to 4.5km (15,000ft). AVO has raised the Aviation Color Code and Alert Level to RED/WARNING. Much higher ash emissions are possible, though relatively uncommon in historical time. Strong explosive eruptions occurred in 1939, 1956 and particularly in 1983 when ash rose to 25,000ft. Note that a very large eruption is extremely unlikely even though Veniaminof had a 50km3 caldera-forming eruption 3,700 years ago.
